The kinetic population balance model (PBM) is widely used to predict the particle size distributions of ball milling products. The matrix model can be easily used for the same purpose if the grinding time can be incorporated into the relevant model. This study proposes and demonstrates an accurate algorithm that uses a pseudo-matrix model to simulate the product size distributions (PSDs) of successive breakage events in batch grinding. The simulation results indicate that the breakage events in the mills may be determined by attraction forces between particles and grinding media. The algorithm is shown to be widely applicable to different combinations of samples and grinding equipment. The algorithm can even work with arbitrary sets of parameters that are irrelevant to the mill feed. Therefore, the proposed algorithm with its mathematical framework may be fundamental to different size reduction methods. Also, the algorithm is shown to have a potential for predicting the product PSDs of continuous milling.

A robust algorithm for configurational-force-driven brittle crack propagation with R-adaptive mesh alignment
MIEHE, CHRISTIAN; Gürses, Ercan (2007-10-08)
The paper considers a variational formulation of brittle fracture in elastic solids and proposes a numerical implementation by a finite element method. On the theoretical side, we outline a consistent thermodynamic framework for crack propagation in an elastic solid. It is shown that both the elastic equilibrium response as well as the local crack evolution follow in a natural format by exploitation of a global Clausius-Planck inequality in the sense of Coleman's method. Here, the canonical direction of the...
A PHD Filter for Tracking Multiple Extended Targets Using Random Matrices
Granstrom, Karl; Orguner, Umut (2012-11-01)
This paper presents a random set based approach to tracking of an unknown number of extended targets, in the presence of clutter measurements and missed detections, where the targets' extensions are modeled as random matrices. For this purpose, the random matrix framework developed recently by Koch et al. is adapted into the extended target PHD framework, resulting in the Gaussian inverse Wishart PHD (GIW-PHD) filter. A suitable multiple target likelihood is derived, and the main filter recursion is present...
A First-Order Linear Model for the Estimation of Detonation Velocity
Türker, Burhan Lemi (Informa UK Limited, 2011-01-01)
A linear multivariable model has been derived for the estimation of detonation velocity. Then, its two simplified forms, first-order linear models, have been proposed as estimators of detonation velocities of a large population of explosives having different skeletal structures. Then, the models are analyzed mathematically and regression equations are obtained and discussed. The first model possesses two independent variables E/M and density, whereas the second one is based on E/M only. The total energy (E)...
A computational framework of configurational-force-driven brittle fracture based on incremental energy minimization
MIEHE, CHRISTIAN; Gürses, Ercan; BIRKLE, MANUEL (Springer Science and Business Media LLC, 2007-06-01)
A variational formulation of quasi-static brittle fracture in elastic solids at small strains is proposed and an associated finite element implementation is presented. On the theoretical side, a consistent thermodynamic framework for brittle crack propagation is outlined. It is shown that both the elastic equilibrium response as well as the local crack evolution follow in a natural format by exploitation of a global Clausius-Planck inequality. Here, the canonical direction of the crack propagation associate...
A comparative study of modeling of radiative heat transfer using mol solution of dom with gray gas, wide-band correlated-k, and spectral line-based weighted sum of gray gases models
Cayan, Fatma Nihan; Selçuk, Nevin (2007-01-01)
A radiation code based on the method of lines (MOL) solution of the discrete ordinates method (DOM) for the prediction of radiative heat transfer in nongray absorbing-emitting media was developed by incorporation of two different gas spectral radiative property models, wide-band correlated-k (WBCK) and spectral line-based weighted sum of gray gases (SLW) models. Predictive accuracy and computational efficiency of the code were assessed by applying it to one- and two-dimensional test problems and benchmarkin...
